In this issue, the editor will bring you a solution to the problem of overlapping color scales of multi-layer objects in big data's data map. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Today's article is a further deepening on the basis of yesterday's push, focusing on how to overlay bubble layers on a map filled with discrete colors.

To make the case consistent, yesterday's dataset is still used.
